How much should I book in advance?

Book your first 3 nights and any specific experiences you can't miss (like Ha Long Bay tours). The rest should stay flexible—Southeast Asia rewards spontaneous travelers with better deals and local recommendations.

Is it safe to travel between countries overland?

Yes, overland border crossings are common and safe. The busiest routes like Bangkok to Siem Reap or Ho Chi Minh City to Phnom Penh have regular tourist bus services. Allow extra time—border crossings can take 2-4 hours including visa processing.

What's the best route for first-time visitors?

Thailand → Cambodia → Vietnam → Laos → Thailand. Start in Bangkok, fly to Siem Reap for Angkor Wat, bus to Ho Chi Minh City, work your way north through Vietnam, cross to Laos, then return to Bangkok. This loop minimizes backtracking.

How do I handle money across multiple countries?

Get a fee-free debit card before you go. Most countries have widespread ATMs. Carry some USD cash for visa fees and border crossings. Exchange apps like XE Currency help track rates across multiple currencies.

Should I book transportation between countries in advance?

Not necessary except during peak season (December-January) or for specific routes like overnight trains. Most routes have daily departures. Book 1-2 days ahead for peace of mind, especially for sleeper buses or boats.

How to plan a multi-country Southeast Asia route

Start with Thailand for easy entry, then move through Cambodia, Vietnam, and Laos in a logical loop to minimize backtracking. Budget 3-8 weeks total and book only your first few nights—flexibility is key for this region.

Pick your entry and exit points. Bangkok is the easiest starting point with the most international flights. Common exit points are Bangkok, Ho Chi Minh City, or Kuala Lumpur. Book your flights into and out of these cities first.
Choose 3-5 countries maximum. Don't try to see everything. The classic route is Thailand → Cambodia → Vietnam → Laos → back to Thailand. Alternative southern route: Thailand → Malaysia → Singapore → Indonesia. Pick based on your interests and time.
Map out your route geographically. Plan to minimize backtracking. Use Google Maps to see actual distances. Bangkok to Siem Reap is 400km, Siem Reap to Ho Chi Minh City is 230km. Factor in border crossing time—budget a full day for each crossing.
Allocate time per country. Thailand: 7-14 days minimum, Vietnam: 10-21 days, Cambodia: 4-7 days, Laos: 5-10 days. Don't rush—2 weeks across 4 countries means you'll spend more time traveling than exploring.
Research visa requirements. Check visa-on-arrival policies for each country. Most allow 30 days visa-free or visa-on-arrival, but requirements change. Vietnam requires advance e-visa for most nationalities.
Book only your first 3 nights. Book accommodation for your arrival city and maybe your second destination. Leave the rest flexible—you'll meet travelers with recommendations and plans change constantly in Southeast Asia.
Plan your transportation. Download 12Go Asia app for booking buses, trains, and boats. Sleeper buses work well for longer routes. Budget airlines like AirAsia connect major cities cheaply—sometimes faster and same price as ground transport.
